IMPROVEMENT IN enem-snrm'rohs.

The Schedule rel'en'ed to in these Letters Patent and maldng part of them To all whom this may concern:

Be it known thatI, A. W. POWERS, of Barrington, in the county of Cook,and State of Illinois, have invented an Improved Seed-Separator; and Ido hereby declare that the following is a full, clear, and exactdescription of the construction and operation of the same, referencebeing had. to the accompanying drawings, and letters marked thereon,snaking a part of this description, in which- Figure 1 is a perspectiveof a seed-separator, or fanning-mill, with my device attaged. v

Figure 2, a longitudinal section of the same.

Figure 3, a perspective view of the division cut on; with itscrank-attachment removed from the other parts of the-separator. 1 I

The uature of the present invention consists in the application ofacut-ofi placed at the tails of the lower sieves, and arranged toconduct seed into a spout, or drawer, at the bottom of the separator;and in an adjustable chute, or shoe, attached to the rear end of theseparator, and arranged to conduct oats and seeds of similar size into ahalf bushel, the upper sieve projecting'over the edge of the chute forthis purpose.- Both devices are operated incombination with the ordinarysieves and shoe of a seed-separatorl To enable othersskilled in the artto fully comprehend the construction and operation of my invention, Ihave marked corresponding parts with similar letters, and will now givea detailed description.

AArepreseut the ordinary separator, which supports a fan, E, and shoe,B, the latter being arranged tolsupport the sieves and screens b e d, inthe usual manner.

0 represents a chute, which is attached to the rear end of the separatorA A, by means of books or staples D, or otherwise as most convenient.

The object of this chute is to conduct oats into a suitable receptacle,placed at or near the side of the separator. The upper sieve b,projecting over the edge of the chute G, prevents the oats from fallingdown at the tail of the shoe B.

When it becomes necessary to conduct other grain into the chute C, itcan be adjusted under the sieve which is below the one shown a tb, bysimply putting additional staples into the separator for supporting thehooks D. I

h 45 represent two drawers, which are placed transversely with theseparator, and they are made to correspond in length with the width ofthe shoe, or they may be ,the full width of the separator.

An inclinedspout, or trough, g, is placed between 'the drawers, and usedto conduct seed into an elevator,

The grain falls 'on the perforated-Zine sieve b, the

wheat passing through the holes, and the oats falling into the chute O.

The wheat, after falling through sieve i), strikes the chute-board c,and is conveyed to sieve d, the remain-- ing oats, if any, falling intodrawer 'i, and, the chess into drawer h, after passing through screen e.

The cut-lofi f is set to make two grades of wheat,

but if it is turned down, as shown by dotted lines J one grade will bemade, the drawer i, in the forifler purpose specified.
